Onkyo Integra P-304 Stereo Preamplifier Unit shows cosmetic wear but has been tested and is in good working condition. The only particular issue I came across is some scratchiness in the balance knob. You usually have to find a bit of a sweet spot and it it tends to cut out if turned all the way to the left. Most likely cleared up with contact cleaner, but I have not opened this unit to investigate. Previous owner scratched their information into the back of the unit and has been covered with electric tape. I also currently have an auction for an Onkyo Integra M-504 Stereo Power Amplifierif interested. Package weighs approximately 20lbs and cost of shipping varies by buyer location. Free Local Pickup can also be made available. Package will be insured for final amount and require signature at delivery.

ONKYO INTEGRA P-304 STEREO PREAMPLIFIER PRE AMP Working, READ description ! Nice cosmetic condition, some normal wear and light scratches on the metal top plate, the faux wood side panels have normal wear and a few scratches, much nicer condition than most that come up for sale. This amp was in a system and is tested and working. That being said I took it apart and it was pretty dusty, I cleaned the boards and got it cleaned up nice. I would assume that due to age that you may want to consider doing some further work to it. Again it is tested and working, but I am selling it AS-IS due to age so please take that into consideration, as the price reflects this as well.

Onkyo Integra M-503 Power Amplifier and Integra P-304 Pre-Amplifier.

If you know, you know. If not, look them up.....Offered for your purchasing pleasure is a matching set of ONKYO Integra components including the MASSIVE M-504 power amplifier with huge dual VU meters and the P-304 pre-amplifier! First and foremost, both work and are ready to use as pictured. TONS OF POWER. Video available. Read on for details: Maintenance consisted of the following:Amp chassis was dustered, was already super clean. See pic.No other cleaning done and no repairs made.The bad:Lighting on amplifier right side VU meter needs attention. Several times when turned on, the lamps would not illuminate. No apparent issues seen inside the chassis. A couple of taps on the outside would bring it on, but only one of the two lamps work. Probably easiest to change out all lamps on both sides, or run as is. Last few times we turned the amp on, the right side lit up immediately. Meter works no problem. See pics.Pre-amp is missing a REC selector knob. Replace one or both, or leave as is.Some spotting on pre-amp. Hard to notice unless youre really up close. We did a general cleaning only, some polishing may remove it. See pics.Testing/The Good:Amp has super clean and clear signal on all four speaker outputs.Tuner, CD and phono inputs are guaranteed working good, no other testing done.Both VU meters work well, bar the aforementioned lighting issue.Rosewood finish end caps are beautiful on both pieces, with some minor scratches on one panel on the amp. See pics. Please ask questions! Remember, this set weighs a ton and will not be easy to ship. Hence the charge. They will be shipped separately. Each will be secured in first box and then boxed again. Both will be insured.
